The free space path loss, also known as FSPLis the loss in signal strength that occurs when an electromagneticwave travels over a line of sight path in free space. In thesecircumstances there are no obstacles that might cause the signal tobe reflected refracted, or that might cause additional attenuation.The free space path loss calculations only look at the loss ofthe path itself and do not contain any factors relating to thetransmitter power, antenna gains or the receiver sensitivitylevels. These factors are normally address when calculating a linkbudget and these will also be used within radio and wireless surveytools and software.
